Part:BBa_K4390026

SB7-tagged M. edulis Metallothionein

This part is not compatible with BioBrick RFC10 assembly but is compatible with the iGEM Type IIS Part standard which is also accepted by iGEM.

Usage and Biology

SB7 is a 7-amino-acid silica-binding motif from the spore coat protein CotB1 of Bacillus cereus. According to studies, its three arginine residues are important for binding to silica surfaces. We tagged this sequence to the N-terminus of the metallothionein of Mytilus edulis. Therefore, when the lysate from a cell culture expressing SB7-tagged metallothionein is mixed with silica beads followed by washing off the supernatant, we would be left with metallothioneins bound to the silica beads. This entire construct could then be applied as an ultrafiltration device for removing heavy metals from the wastewater. This is one of the three types of silica-binding tags we explored for immobilising proteins to silica beads.
